Samarium and a catalytic amount of iodine were used to obtain functionalized cyclopentenes by reductive dimerization followed by intramolecular cyclization of 1, 1-dicyanoalkenes under mild conditions.
Active metal bismuth is produced in situ via Sin/BiCl_3, system in aqueous media. Promoted by this active species. β-aminoesters and α-selenoesters are synthesized via reaction of α-bromoesters with 1 -(α-aminoalk...Active metal bismuth is produced in situ via Sin/BiCl_3, system in aqueous media. Promoted by this active species. β-aminoesters and α-selenoesters are synthesized via reaction of α-bromoesters with 1 -(α-aminoalkyl ) benzotriazole and diselenides in moderate to good yields.展开更多
